Clinical significance of SBI
To identify the clinical significance of SBI, Knipp et al. evaluated
new-onset SBI and postoperative cerebral function after on-pump CABG
surgeries by MRI. Moreover, they reported that in the group with SBI,
cognitive deterioration was observed during the acute postoperative
period compared to the group without SBI 8. Sun et al.
showed that postoperative delirium was associated with SBI5. This condition can occur when SBI occurs in the
frontal lobe or in areas correlated to cortical speech or mental
activity. Vermeer et al. 9 revealed that the risk of
dementia increased with spontaneous SBI, and the decline in cognitive
function was steep. The occurrence of SBI after cardiac surgery may also
affect long-term life expectancy and healthy life expectancy. In the
current study postoperative delirium and the cognitive function was not
quantified. We believe further research and follow-up are required for
patients with postoperative SBI.
